TYPE-BAR.

Application filed October 23, 1901.

faces thereof, thus enabling a number of bars to be closely assembled,or piled up fairly and solidly.

This result I accomplish by providing a number of grooves or depressionsin either one or both of the side faces of the bar, which grooves arerelatively narrow as compared with the portions of the face of the barbetween them and which contact with the side face of an assembled andcontiguous bar. Upon rubbing adja cent bars together these faces willslide one upon the other and any particles of dirt or like matteradhering to the side of the bar will gradually be worked off into thenarrow grooves, thus permitting the bars to lie together in closecontact.

In the drawing accompanying the present specification, Figure 1 is aside elevation of a typebar embodying my present improvements, thegrooves or channels being formed only on one side face thereof and partof the bar depthwise thereof being broken away. Fig. 2 shows theopposite side of the bar, which in the particular form and structure ofbar shown, is unprovided with grooves. Fig. 3 is a perspective view ofthat portion of a typebar below the printing portion thereof, the samebeing provided upon one of its faces with relatively narrow grooves orchannels, as in Figs. 1 and 2. Fig. 4 is a cross-sectional view througha pair of assembled typebars or typebar-blanks, such as set forth inFigs. 1 to 3 inclusive, showing the relation which the grooves may bearto each other. Fig. 5 is a view similar to Fig. 4, illustrating thatconstruction of a tybebar or typebar-blank in which each side facethereof is provided with a relatively narrow groove, the groove on oneface being disposed between adjacent grooves on the opposite face.

Similar characters of reference designate corresponding parts in allfigures.

This invention may be said, in general to involve a construction for thebody portion of a typebar in which grooves or channels are made ineither one or in both of those faces of the bar which contact with acontiguous face or faces of other bars when assembled there with. Thisbody portion may constitute an integral part of the typebar, or it mayform one component of Specification of Letters Patent.

a composite bar. It may also constitute the body portion of a blank fromwhich a typebar is to be made.

Referring to Figs. 1, 2, and 3, B designates a typebar, which in thisinstance is a one-piece bar, although the present invention is notlimited in its application to typebars of any particular character ornature, as they may be of integral or composite form and of a cast metalor of a relatively ductile metal upon whose edge the types are formeddirectly by some suitable process, such for instance, as one capable ofproducing wrought types. The various types are designated withoutpreference by t.

The grooves 2 in the side face of the bar preferably extend at an angleto the horizontal axis or line of length thereof, the angular relationbeing, in the illustrated relation, a substantially right-angled one.These grooves 2 preferably extend from top to bottom of the bar and arerelatively narrow, as clearly illustrated, thus leaving comparativelylarge areas between them with which the adjacent bar contacts when thebars are assembled.

A typebar having grooves or channels of this relatively narrow width andcomparative great separation one from the other is distinctly differentfrom constructions in which either one or both of the side faces of thebar is provided with projections located at comparatively greatdistances apart, which projections contact with the contiguous bar whenthe bars are assembled. In this latter case the area of contact iscomparatively small and the bar or body portion is extremely liable tobend between the two adjacent lines of contact along the projectingportions. This objection, however, is not present in the barsconstructed according to the present invention, since, as before stated,

the grooves being comparatively narrow do not give rise to an absence ofcontact over an unduly wide distance measured lengthwise of the bar.When two bars so constructed are rubbed together, therefore, while incontact, dirt or foreign matter on the faces of the bars is readily andrapidly worked into the grooves 2, thus enabling the bars'to be pressedinto close contact.

Although in Figs. 1, 2, 3, and 4 these grooves 2 are shown only in oneside face of the bar, evidently they may also be made upon both facesthereof. This construction is set forth in Fig. 4, in which the grooves2 upon the two faces are not, however, as shown, disposed directlyopposite each other, but are staggered, that is, the grooves upon oneface are located between the grooves upon the opposite face.

In using the term typebar it will be understood that the termtypebar-blank is also included.

Having described my invention, I claim 1. A typebar provided withdirt-collecting grooves or depressions of comparatively narrow width inits side face.

2. A typebar provided with dirt-collecting grooves or depressions ofcomparatively narrow width in its side face, which grooves ordepressions are disposed at an angle to the line of length of the blank.

3. A typebar provided with dirt-collecting grooves or depressions ofcomparatively narrow width in its side face, said grooves or depressionsextending substantially in line with the vertical height of the blank.

4. A typebar provided with dirt-collecting grooves or depressions in itsside face, the width of which grooves or depressions is less than thewidth of the surfaces between adjacent grooves or depressions, and whichcontact with an adjacent bar when the bars are assembled.

5. A typebar provided with dirt-collecting grooves or depressions in itsside face, the width of which grooves or depressions is less than thewidth of the surfaces between adjacent grooves or depressions, and whichcontact with an adjacent bar when the bars are assembled, and saidgrooves or depressions extending substantially in line with the heightof the bar.

6. A typebar having dirt collecting grooves or depressions ofcomparatively narrow width in both of its side faces.

7. A typebar having dlrtcollecting grooves or depressions ofcomparatively narrow width in both of its side faces, said grooves ordepressions on one face being located between the grooves or depressionson the opposite face.

8. A typebar having dirt-collecting grooves or depressions ofcomparatively narrow width in both of its side faces, said grooves ordepressions on one face being located between the grooves or depressionson the opposite face, and all of said grooves or depressions extendingsubstantially in line with the vertical height of the bar.

9. A typebar having dirt-collecting grooves or depressions ofcomparatively narrow width in both of its side faces, said grooves ordepressions on one face being located between the grooves or depressionson the opposite face, and all of said grooves or depressions extendingsubstan tially in line with the vertical height of he bar. and saidgrooves or depressions each being of a w th less than the portion of theside face of the blank intervening between adjacent grooves.

10. A typebar having dirt collecting recosSes of comparative narrowwidth at a comparatively wide distance apart in its side face.

11. A typebar having dirt-colleeting recesses of comparative narrowwidth at comparative wide distances apart in both of its side faces.

12. A typebar having dirt collecting grooves of comparative narrow widthat comparatively wide distances apart in each of its side faces, and therecesses at one side being opposite the face on the other side, wherebywhen several of these are assembled, the recesses o1 one will scavengethe faces of those juxtaposed.

3. A typebar having dirt collecting recesses in its sides ofcomparatively narrow width and the recesses on oppo site sides beingdifferently disposed whereby when several of these are assembled thegrooves of one will scavenge the others.

sembled the grooves on contacting side faces will be out of register.
